Legend of Grimrock

I just bought this in the sale and installed it with no difficulties. However, when attempting to play, I receive the 'preparing to launch...' notification but the game does not start. If anyone else has this problem and/or knows how to fix it, help would be appreciated.

I had exactly the same problem, reinstalling directX did not help. But when I ran the game directly, not from Steam (go to the game directory and start gimrock.exe) it did show an error message about missing msvcr100.dllThis dll is part of Visual C++ redistributable, installing the 2010 version from microsoft support pages helped:http://www.microsoft.com/en-us/download/details.aspx?id=5555
